  • Nothing is uploaded

    Processed entirely in your browser. Your files never leave your device.

  • No signup needed

    Open the tool and go. No account, no email.

JPG is the format cameras and phones save photos in, and the one upload forms, email and print services expect. It is also the format that compresses best: because JPEG is lossy by design, lowering its quality setting a little removes a lot of weight. A 5 MB photo straight off a phone commonly comes back between 500 KB and 1.5 MB and looks the same at normal size.

This JPG compressor only takes JPG and JPEG files and always hands back a JPG, so nothing changes format behind your back. It runs entirely in your browser: the photo is not uploaded, there is no size limit beyond your device's memory, no account and no watermark.

How to compress a JPG

  1. Add your JPG

    Drag a .jpg or .jpeg file into the box, or click to browse. On a phone you can pick it straight from your photo library.

  2. Set the quality

    80% is set for you and suits most photos. Slide lower for a smaller file, higher to keep more fine detail.

  3. Compress and download

    Press Compress JPG. The result shows the new size and the percentage saved before you download, so you can try another setting first.

JPG and JPEG are the same format

The two names describe one standard from the Joint Photographic Experts Group. The shorter .jpg extension dates from early versions of Windows, which only allowed three letters; Macs and Linux used .jpeg. Compressing a JPEG and compressing a JPG is therefore the same job, and this page treats both identically.

Your file keeps its format: a JPG goes in and a JPG comes out, named after the original with “-compressed” added, so the two are easy to tell apart in your downloads.

How much can you compress a JPG without losing quality?

JPEG compression discards detail the eye is least likely to notice — fine texture in busy areas, subtle colour variation — and the quality setting decides how much. Between 75% and 90%, almost every photograph looks identical to the original at normal viewing size while losing half or more of its weight.

Below about 60% the compromises start to show: soft edges, blocky patches in skies and flat walls, and faint halos around high-contrast lines. Text, screenshots and logos show them sooner than photos do, so give those a higher setting.

Every JPEG save is a new lossy pass. Compress once from the best copy you have, rather than compressing an already-compressed file again and again.

Getting under 1 MB, 500 KB or 100 KB

Many forms cap uploads at 1 MB, 500 KB or even 100 KB. Quality alone usually gets a phone photo under 1 MB. For the smaller limits, the dimensions matter more than the quality setting: a 4000-pixel-wide photo has sixteen times the pixels of a 1000-pixel one.

So if the result is still too big, resize the photo first — 1600 or 2000 pixels on the long side is plenty for the web and for email — then compress it here. The two savings multiply, and the result card tells you the exact size before you download.

Which JPG quality to choose

A rough guide for a typical phone photo. Results vary with the picture, which is why the exact size is shown before you download.

When to compress a JPG

  • An upload form rejects the file

    Job applications, government portals and marketplaces often cap JPGs at 1 or 2 MB. Compressing is the quickest fix.

  • Photos on a website

    Oversized JPGs are one of the most common reasons a page loads slowly. Lighter photos mean faster pages and better Core Web Vitals.

  • Emailing a batch of photos

    Attachment limits add up fast with full-size camera photos. Compressed JPGs fit several to an email.

  • Freeing up storage

    Compressing photos you keep for reference, rather than print, saves a lot of space in cloud storage and on your phone.

Frequently asked questions

How do I compress a JPG for free?
Drop the JPG into the box above, keep the quality at 80% or adjust it, and press Compress JPG. There is no sign-up, no watermark and no limit on how many photos you compress.
Does compressing a JPG reduce quality?
Technically yes, because JPEG is lossy — but at 75% and above the difference is not visible at normal size on almost any photograph. Compare the preview with the original before you download if you want to be sure.
Can I compress a JPEG file as well?
Yes. JPEG and JPG are the same format with two different extensions, and both are accepted here and compressed in exactly the same way.
How do I reduce a JPG to under 1 MB or 100 KB?
Start with the quality slider: most phone photos drop under 1 MB at 70–80%. For 100 KB, resize the photo to around 1000–1200 pixels wide first, then compress. The result card shows the exact size before you download.
Why did my compressed JPG come out larger?
The original was already compressed harder than the setting you chose. Lower the quality, or keep the original — it is already about as small as it will get.
Is my photo uploaded to a server?
No. The compression runs on a canvas inside your browser tab, so the photo never leaves your device.
Does compressing remove EXIF data and GPS location?
Yes. The JPG is re-encoded from its pixels, so metadata such as camera model, timestamps and GPS coordinates is not carried over. The photo keeps its correct orientation.
Can I compress PNG or WEBP files here?
This page takes JPG and JPEG only, so the result is always a JPG. For PNG use Compress PNG, and for a mix of formats use the general image compressor.
